GK125 Go Magnum 125cc Go Kart

GK125-9 Go Magnum Go Kart – 125cc, Fully Automatic with Reverse

The GK125-9 Go Magnum is a robust recreational go kart built for both fun and practical use. It’s powered by a 125cc single-cylinder, 4-stroke, air-cooled engine that delivers strong torque for off-pavement thrills and reliable performance in tighter tracks.

This go kart uses a fully automatic transmission with reverse, making it easy to operate with no shifting required. The electric start system with CDI ignition ensures quick startups. Braking is handled via hydraulic disc brakes on both rear wheels for consistent and safe stopping power.

Standing on rugged 13×5-6 all-terrain pneumatic tires, the GK125-9 grips dirt, grass, and light trails with confidence. Its frame includes a roll cage, side netting, and dual lap belts for rider protection. The seating is designed for two riders side by side. It also features a tubular steel chassis and reinforced suspension for durability.
